Algae blooms into promising biofuel

WASHINGTON, July 26 (AFP): Some call it pond scum, but algae is drawing increasing attention as a source of biofuel that can help replace petroleum or fuels made from crops like corn or soybeans.
The notion of using algae to produce fuel has been around for decades, but has garnered new interest and investment amid a search for energy sources that will limit carbon dioxide emissions blamed for climate change.
